Manufacturing in the UK is undergoing significant transitions and transformations in terms of new emerging technologies and methods. The traditional view of using a range of disparate processes in a precisely defined logical sequence of steps is now being challenged by the continued emergence and growth of metal additive layer technologies, most commonly termed additive manufacturing. With projected growth in this sector increasing (current annual compound growth rate is 34.9%), it's continued involvement in manufacturing is set to increase considerably. However, the major bottleneck is the significant additional finishing processes required after initial generation of the component. The streamlined and integrated combination of AM and subtractive process is now being termed hybrid manufacture. Current design for manufacture methods are well-established techniques that allow designs to be adapted to enable efficient production using traditional linear manufacturing approaches. However these current state of the art methods are not directly applicable to new emerging manufacturing techniques, without significant modification and adaption. This will impede the generation and uptake of novel and emerging manufacturing processes, further stagnating design. Project DHarMa (Design for Hybrid Manufacture) aims to deliver a disruptive, design rationale and process that is specifically targeted at enhanced utilisation of combined additive and subtractive technologies in the form of hybrid manufacture (HM). This will be achieved by undertaking systematic, quantitative and qualitative research that will focus on generating a design for hybrid manufacturing process, based on identified design features and geometry classifications in seamless conjunction with hybrid manufacturing key performance indices and a manufacturing capability framework. DHarMa will incorporate specific additive and subtractive manufacturing information constructs in conjunction with design feature and geometry relationships and attributes. Essentially this will integrate and categorise part specific design and manufacturing information and will be used to generate the DHarMa process.Designers will have a powerful tool that will enable them to tailor and adapt their designs to be manufactured using a combination of additive and subtractive technologies. Unlike conventional manufacturing that has significant limitations in terms of features and geometries that can be correctly generated, AM un-constrains manufacturing with the direct capability to create highly complex features and geometries that would be typically inaccessible using conventional methods (for example, dematerialised internal thin walled features). This affords the designer more design freedom and flexibility, thus empowering them to create new innovative products without the need to be constrained by a rigid set of conventional manufacturing protocols. This feasibility project will provide the initial study in to the generation of a design process that will enable parts to be specifically designed for manufacture using a HM approach. This will initially be based on prismatic designs that will be applied to HM.

英国的制造业正在经历新的新兴技术和方法方面的重大转型和变革。以精确定义的逻辑步骤顺序使用一系列不同工艺的传统观点现在受到金属增材层技术（最常称为增材制造）的持续出现和发展的挑战。随着该行业的预期增长（目前的年复合增长率为34.9%），它对制造业的持续参与将大幅增加。然而，主要的瓶颈是在初始生成组件之后需要显著的额外精加工过程。增材制造和减材制造的流线型和一体化组合现在被称为混合制造。当前的制造设计方法是成熟的技术，其允许设计被调整以使得能够使用传统的线性制造方法进行高效生产。然而，这些现有技术的方法在没有显著修改和调整的情况下不能直接应用于新出现的制造技术。这将阻碍新的和新兴的制造工艺的产生和吸收，进一步停滞设计。DHarMa项目（混合制造设计）旨在提供一种颠覆性的设计原理和过程，专门针对混合制造（HM）形式的组合增材和减材技术的增强利用。这将通过进行系统的，定量和定性的研究，重点是产生一个设计的混合制造过程中，确定的设计特点和几何分类与混合制造的关键性能指标和制造能力框架无缝结合的基础上。DHarMa将结合设计特征和几何关系及属性，采用特定的增材和减材制造信息结构。从本质上讲，这将整合和分类零件特定的设计和制造信息，并将用于生成DHarMa过程。设计师将拥有一个强大的工具，使他们能够定制和调整他们的设计，以使用增材和减材技术的组合进行制造。与在可以正确生成的特征和几何形状方面具有显著限制的传统制造不同，AM不限制制造，直接能够创建使用传统方法通常无法访问的高度复杂的特征和几何形状（例如，非物质化的内部薄壁特征）。这为设计师提供了更多的设计自由度和灵活性，从而使他们能够创造新的创新产品，而不需要受到一套严格的传统制造协议的约束。该可行性项目将为设计过程的生成提供初步研究，该设计过程将使零件能够使用HM方法专门设计用于制造。这最初将基于将应用于HM的棱柱形设计。
